The first wave power patents were applied for in 1799. Since then man has dreamed of using this seemingly unlimited source of energy for practical applications. To date, none of these attempts have proven to be commercially successful.
Currently applications are approved for units in the ocean near Oregon and California (San Fransisco). There is also an experimental wave farm in Portugal. This unit began operating in 2008 and had some power generated for the two months it was opened. It was shut down permanently in November of 2008. Attempts are being made to find investors to try reopening this farm after solutions are believed to have been made for some of the operating issues of the plant.

I don't know for certain but I expect wind power is the least widely used (wave power and tidal power are not used commercially at all yet, I believe). A lot depends on your definition of 'widely used'. Do you mean megawatts generated in a given time?
Yes

Natural Resources are used to make everything on the planet. The ocean is a natural resource, and it can be used to generate wave power.
wave power is efficient.
A wave power machine is a generator that is powered by wave power. This is a piece of equipment that converts wave variances in a body of water and converts this into electric power.
In most circumstances a full wave diode bridge is used to convert AC into DC. Along with inductors and capacitors used as filters, the DC ripple is smoothed out to a very stable DC voltage. This is the method used in DC power supplies. To convert from DC to AC an inverter is used. Today most inverters use the modified sine wave method which brings the sine wave closer to a AC generated sine wave. Older inverters used an on - off switching procedure to generate a square sine wave. Modern electronics do not work well with square wave generation.
A wave trap is an object used in power line communications that is made up of several resonant circuits. A wave trap protects the power line from crashing by preventing high frequency waves from coming through.
